.UPDATE...The biggest update to the forecast this evening was to
issue a Wind Advisory for the East Puget Sound Lowlands, which
includes (but is not limited to) the cities of: North Bend,
Covington, Enumclaw, and Bonney Lake. This is largely based on
recent observations along with Spotter reports (thank you for the
reports!) Although cities north of these locations have been
included in the Advisory, think winds will be strongest near the
cities listed above. East winds sustained 25 to 35 mph with gusts
to 45 mph will be possible through midnight. Winds may be strong
enough at times to bring down trees and powerlines.

Aside from the Wind Advisory, also dropped snow levels a tad
tonight thru Wed morning. The rest of the forecast looks good.

Water vapor imagery this evening reveals closed low pressure over
the offshore waters of WA and OR, while at the sfc, a frontal
boundary also resides just offshore/near the Coast. Lift supplied
by the upper trough, along with frontogenetical forcing is
allowing for widespread stratiform precip to spread over the area
this evening. Have received reports of snow near the Coast as well
as the eastern Olympic Peninsula as precip spreads into a cold
environment, characterized by snow levels below 500ft. Closer to
Puget Sound, dewpoint depressions remain rather large as easterly
winds off the Cascades contribute to a dry lower level air mass.
Despite this, still receiving reports of light snow/flurries
across portions of Puget Sound as this update is being typed. NAM
and GFS Bufr soundings remain rather aggressive in keeping this
low level dry air in place through much of the night. This would
prevent much in the way of snow reaching the surface, although it
is possible as the column slowly saturates that there may be a
brief window Wed morning where snow is possible around the Sound.
Aside from this, the snow forecast remains on track, with
easterly upslope flow favoring the Hood Canal/Eastern Peninsula
and  the heaviest snowfall totals during this event.

Previous discussion provided below with an updated marine and
aviation section.

.PREV DISCUSSION... /issued 229 PM PST Tue Jan 26 2021/

.SYNOPSIS...Western Washington will remain in a bit of a trough-y
pattern the next few days. A series of fairly weak fronts will be
associated with these troughs that move through the area. The
general trend in precipitation with each of these fronts will be
mostly light and scattered. After tonight, snow levels begin to
rise throughout the week.

&&

.SHORT TERM /TONIGHT THROUGH FRIDAY/...Clouds ahead of the cold
front that currently situated just off shore will continue to move
in this afternoon. As this front moves through expect it to
produce some precipitation over the area. The precipitation type
is going to be very dependent on location. With temperatures in
the low to mid 30s tonight for much of the lowland areas and
strong easterly flow coming down from the Cascades snow
accumulation is unlikely for much of the East side of the Puget
Sound and Northern Inland waters. However, locations above 500
feet on the East side of the waters have a greater chance of
seeing a dusting of snow overnight. With the easterly winds, some
terrain enhancement of the precipitation is expected on the East
side of the Olympics, including the Hood Canal area. A few inches
of snow is expected above 500 feet, with more accumulation as you
go up in elevation. However, there still remains some uncertainty
with the snow totals in this area. It will very much depend on
temperature, precipitation intensity as well as how strong those
easterly winds will be in this area. Outside of the precipitation,
the winds tonight will have to be monitored carefully. With a
pressure gradient ~10 hPa across the Cascades the potential for
some stronger winds is there. This is especially true for areas
that lie within the Cascades gaps from Enumclaw to North Bend. By
mid morning Wednesday the weather is expected to be calming down
and skies will be scattering out, but a few remaining scattered
showers are expected to remain in place. Additionally, snow levels
will begin to rise up to 1500-2000 feet by the afternoon. These
snow levels are expected to stay pretty much in place for the
remainder of the week, therefore, ending the lowland snow threat
for awhile. The next front is expected to move through the area
Thursday night. But with the main part of the trough well to our
south, Western Washington is expecting mostly light scattered
precipitation.

.LONG TERM /SATURDAY THROUGH TUESDAY/...This weekend we should
see a little bit of warming, with high temperatures in the
lowlands going to be in the mid to upper 40s. A more organized
front will move through Saturday into Sunday. Rain in the lowlands
and mountain snow are expected. The bulk of the precipitation is
expected to be along the coast and over the Olympic Mountains.
There is still a lot of uncertainty and many things can change but
right now only 5-8 inches of snow are expected at the Cascade
passes from Friday to Sunday night. The system to watch will be
the one expected Monday into Tuesday. As models are suggesting the
low will track right through Western Washington.

.AVIATION...Precipitation has begun to overspread the area this
evening and is beginning to affect some of the TAF sites. the
majority of the sites are hanging onto VFR, with KHQM and KOLM the
exception with MVFR within the heavier precip. Expect sites to
generally hang on to lower-end VFR conditions, with periods of
MVFR possible. The biggest concern will be the potential for snow.
Right now, TAF sites near Puget Sound (including KSEA) have the
lowest potential for impactful snow given dry easterly winds.
Light snow showers, however, will still be likely. Remaining TAF
sites have a better potential for snow overnight, but
accumulations are not expected. Winds will have an easterly
component thru the period, generally 5-10kts. KSEA, KBFI, and KPAE
likely to see sustained winds 10-15kt with gusts to 25kts this
evening and thru midnight.

KSEA...VFR ceilings dominant tho could see periods of MVFR. Light
precipitation overnight/Wed morning, falling as light snow at
times with no accumulation expected. Winds E/SE 10-15kts with
gusts 25 mph thru midnight, easing to 5-10kts overnight and
Wednesday.

MARINE...The only change to the marine forecast was to extend some
of the small craft advisories over the interior waters through 18z
Wed and to tag on a SCA after the Gale Warnings for the offshore
waters and the W Strait Wed morning. The current forecast remains
on track. Previous discussion below:

Offshore flow will continue with speeds increasing as
weather system passes through. Gales still expected for the coastal
waters this afternoon through tonight with gales for the western and
central portions of the Strait of Juan de Fuca already occuring at
Race Rocks as per latest obs. Small Craft Advisory winds still
expected for the other waters this evening and tonight as front
passes through. Inherited headlines look good and will remain in
place. Winds will decrease late tonight and Wednesday. Fraser
Outflow possible Thursday into Thursday night. Additional fronts
will move through late this week and into this weekend.

Seas of 9 to 12 feet will increase tonight to 9 to 16 feet and
diminish a bit Wednesday and through the week. 18
